The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron.
Bessemer licensed the patent for his process to five ironmasters, but from the outset, the companies had great difficulty producing good-quality steel. [19] Mr Göran Fredrik Göransson , a Swedish ironmaster, using the purer charcoal pig iron of that country, was the first to make good steel by the process, but only after many attempts.

Frederick W. Taylor, recognizing the inefficiencies introduced by some production lines, proposed that by studying the motions and processes necessary to manufacture each component of a product, reorganizing the factory and manufacturing processes around workers, and paying workers piece rates would allow great gains in process efficiency ...
Manufacturing process management (MPM) is a collection of technologies and methods used to define how products are to be manufactured. MPM differs from ERP/MRP which is used to plan the ordering of materials and other resources, set manufacturing schedules, and compile cost data.
An eponymous disease is a disease, disorder, condition, or syndrome named after a person, usually the physician or other health care professional who first identified the disease; less commonly, a patient who had the disease; rarely, a literary character who exhibited signs of the disease or an actor or subject of an allusion, as characteristics associated with them were suggestive of symptoms ...
